Couple things going on here.

The check light "on" means no AC and no propane fire.
12 VDC is required for "propane fire" so if your battery died you might have enough DC to turn on an LED but not run the control board.

it appears that the freezer has to get down to temerature before the ammonia solution starts dropping the temperature in refrigerator section. it would be interesting to learn how to work on them. after 24 hours it seems to be working well. thanks for all the help.
